Description

Technical Field

[0001] The utility model relates to a socket with a safety door. Background Art

[0002] A socket with a safety door is an electrical device that adds a safety protection structure inside the socket, which is designed to prevent foreign objects (especially children's fingers or metal objects) from accidentally inserting into the socket hole, thereby avoiding electric shock accidents.
